Andrew Strauss has admitted that Middlesex have struggled to adapt their Twenty20 tactics to suit Antiguan conditions during the ongoing Stanford Series.

England's Twenty20 cup holders have already lost their opening two matches and will look to arrest that trend when they take on the Stanford Superstars on Thursday.

The England Test batsman admitted that Middlesex had not played as well as they might on the slower surfaces experienced in the Caribbean.

He also said that the conditions required a different approach, with powerplay periods more about consolidation rather than hitting big.

"All teams have struggled to hit boundaries," Strauss said. "Certainly in England you really target those first six overs as the time to add impetus to the innings and get momentum going.

"But here you've got to keep yourself in the game, keep wickets in hand, and generally it's the final five overs people start to hit the boundaries.

"No excuses from us; these are definitely different wickets here to what we play on in England, we just haven't adjusted quickly enough to them."

In their two games so far, Middlesex failed to chase England's total of 121-4 and then suffered a five-wicket defeat at the hands of Trinidad and Tobago after setting them a 118-run target.

Ahead of the Champions League tournament, to be played in India between December 3-10, Middlesex can use their match against the Superstars to work on their approach.

However, England commitments mean that Strauss will be absent from that event.

The 31-year-old currently finds himself in the awkward-sounding position of competing against England Test team-mates who will have the chance to make US$1 million each when they play the Superstars at the weekend.

Nevertheless, Strauss added that he did not feel as though he was missing out.

He said: "I haven't been involved in the one-day set-up for a couple of years, so it is not as though I was left out yesterday.

"If that was the case you would be pretty sad, wouldn't you?

"I am delighted for the lads to have this opportunity but with that opportunity comes a lot of pressure as well.

"It's a great advert for the game that we have high-quality teams playing against each other."
